I have a 2004 WRX and its smoking blue from the tail pipe(oil).. I was wondering if i can get a 2nd oppinion about the issue on here. here is what happens:
Start car normally: no smoke
drive car normally: smoke at stop once car is warmed up (not all the time) reving the motor causes more smoke when the issue is present. However after a couple of quick revs the smoke has stopped (at least visibly)
drive car hard: same as above but with more smoke. at first this only happened on occasion, but now it is everytime i let the car idle at stop (or run on the TT).
My assumption is bad seals on the turbo. I have not taken it apart yet, and it is covered by warranty (lets see how that goes). Only other 2 things i could think of are vavle seals (dunno if this would apply since this is an H4), or <gulp> piston rings.
Car has a 3" exhaust, but no EM or boost controllers besides stock. the only thing i have done differently is the switch from M1 15-50 to Amsoil 20-50 (and this last one was Amsoil 10-40 for winter).
any ideas would help. i have already found another turbo, but an engine will not be easy (providing the dealership does not want to fix)
thanks in advance,
Joe
